In the selection of floor heating leveling materials, ceramsite and pisolite are relatively common materials, and they each have their own advantages and disadvantages.
Ceramsite is a lightweight aggregate with the characteristics of light weight, low thermal conductivity and low water absorption. It can effectively reduce the load on the floor and improve the efficiency of the floor heating system. At the same time, ceramsite has low water absorption and will not cause damage to the floor heating system due to water absorption. However, the price of ceramsite is relatively high and construction is difficult.
Pisolite is a natural aggregate with low price and high thermal conductivity, which can effectively improve the efficiency of underfloor heating systems. At the same time, the construction of the pisolite is relatively simple and the leveling work can bebe carried out quickly. However, pisolite has a high water absorption rate and if not waterproofed it can damage the underfloor heating system.
Therefore, when choosing leveling materials for underfloor heating, you should choose based on the specific situation. If you need high efficiency of underfloor heating system and good construction quality, you can choose ceramsite; If you need low price and fast construction speed, you can choose pisolite. At the same time, it is necessary to fully understand the materials before construction and select appropriate materials for construction.
Whether 4-8 or 8-12 pisolite is better for underfloor heating in the north?
Approximately 0.9 cubic meters of pisolite. Usually, one square meter of backfill for underfloor heating requires 0.015 cubic meters of pisolite, car one square meter of backfill for underfloor heating requires cement, sand and pisolite, and the quantity ratio is 1:2:3. Assuming the thickness of the embankment is 0.03 meters, the total volume is 0.03 cubic meters. The volume of each portion is 0.005 cubic meters, so we can calculate that pisolite is 3 times 0.005 equal to 0.015 cubic meters. Then, multiply it by 60.
What diameter of pebbles should be used for the installation of underfloor heating?
8 to 12.
Northern floor heating generally uses 8-12mm natural pisolite, because the surface of 8-12mm pisolite is smooth, without edges and corners, and the size particles is uniform.
Pisolite refers to a kind of modern-day building material. It is a stone the size of a soybean. It is generally used for floors and roofs. The particle size is similar to thate mung beans and is called stone powder in some places.
What is the difference between button stone leveling for underfloor heating and melon seed leveling?
Special button stone for underfloor heating backfill the ground, the required size is about 10mm, the surface is smooth, no edges and corners, only smooth, thermal conductivity is good. The better and more efficient Linyi paving stone production base in Shandong, a producer of pisolite for underfloor heating, uses natural pisolite, which is filtered twice. is 50 kilograms according to the ratio of cement, sand and pisolite 1:2:3 to finish. Say the important things three times, 10mm, 10mm, 10mm.
Pea stone is smooth and will not damage the floor heating pipe, but its price is relatively high.
1. Smooth button stone will not damage the heating pipe par the ground, but the price is relatively high. Pisolite concrete uses pisolite as underfloor heating backfill to protect underfloor heating coils. The natural silicon content of pisolite gives underfloor heating better thermal conductivity. Floor heating leveling is cheap 50-80 yuan/㎡, expensive 100 yuan/㎡ or even more.
2. Melon seed slices are cheap, but their irregular shape and sharp edges will scratch the heating pipes during the construction of the underfloor heating embankment and during their subsequent use. Over time, there will be hidden dangers of water leakage.
